Compositions of fluorinated fluids and fluorinated surfactants with densities near unity
View Patent ↗This invention provides combinations of fluorinated oils and fluorinated surfactants that have densities of approximately unity (1.0±0.1 kg/liter), where the combination allows the surfactant to dissolve (at least) to 1-2% level (by volume) in the oil.
